BENEFITS OF DSG™ TECHNOLOGY

The DSG™ (Dynamic Surgical Guidance) Technology is based on the principle that the electrical conductivity of tissue varies by the type of tissue. Electrical conductivity is the property of a material to conduct an electrical current. E.g.,:

Cortical bone has low conductivity

Cancellous bone has medium conductivity

Periosteum and blood have high conductivity

This parameter, varying conductivity, can be very helpful in differentiating between various tissue types while drilling a pedicle prior to screw placement.

All PediGuard® Probes have the DSG™ Technology built into them. So, by using the PediGuard® Probes to prepare the pedicles in the spine (prior to implant placement), all inherent benefits of the DSG™ Technology are realized.

How does the PediGuard® Probe work?

A bipolar sensor is embedded at the tip of each PediGuard® probe. A low frequency and low voltage current is pulsed through an electrode in the probe. Based on the local conductivity, the sensor can accurately inform the surgeon of the type of tissue the tip is in. This in turn can alert the surgeon prior to a cortical breach during pedicle preparation. The surgeon is informed in real time of the tissue type by changes in the pitch and cadence of an audio signal and a flashing LED light.

All PediGuard® probes have been programmed such that they will emit an audio signal of:

Low pitch at a slow cadence in cortical bone

Medium pitch at a medium cadence in cancellous bone

High pitch at a fast cadence in periosteum and blood

PediGuard® Probes do not use any ionizing radiation. So, the patient, the surgeon and hospital staff are all preemptively protected from any exposure to such potentially dangerous radiation. Also, PediGuard® Probes provide real-time feedback that does not depend on or require any pre-operative imaging.

Clinical Evidence:

The benefits of the DSG Technology have been demonstrated in a wide number of clinical studies.
